WELL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 440,924, dated November18, 1890.

Application filed August 8, 1888- To all wiwm it may concern.-

Be it known that I, GUSTAVUS PEOH, a citizen of the United States,residing at Storm Lake, in the county of Buena Vista and State of Iowa,have invented certain new and useful Improvements in ell DrillingMachines; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to well-drilling machines; and its object is toincrease the efficiency of the machine and give the operator Theinvention consists of certain details of construction hereinafter setforth, and particularly pointed out in the claims.

In the accompanying drawings, Figures 1 embodying my improvement-s. Fig.3 is a plan. Fig. at is a view of the walking-beam, and Fig. 5 shows thetripping dog or crank.

The same letters refer to corresponding parts in all the views.

The frame of the machine is composed of two sills A, united bycross-girts A. At one end of the frame is a pair of upright booms B,pivoted on a horizontal shaft 0, and constituting shears to support thedrill, being steadied by guys in the usual manner. The upper ends of thebooms are not shown in the drawings; but it is enough to say that theyare united at the top and have fastened to them a double pulley-block,over which run the ropes D and E. These shears are a common feature inwell-drilling machines, and need no further description.

The rope D is attached to the drill. (Not shown.) It runs from the drillup over one of the pulleys at the top of the shears, and thence downunder a pulley F, journaled in the outer end of a swinging arm or leverG,

ably journaled in the projecting ends of the straps b, fastened to theshears B a few feet above the frame of the machine. On the shaft 11 is apulley I, over which the rope D passes to a drum K, the shaft of whichis Serial No. 282,262. (No model.)

mounted in bearings on the sills A near the foot of the shears.

Power is supplied to the machine from a horse-power or other source, andis communicated to the transverse main shaft L, running in bearings onthe sills A. A gear-wheel L imparts motion through a pinion L to afly-wheel M, which gives steadiness to the movements of the variousparts. Near each end of the shaft L is a sprocket-Wheel N N, looselymounted on the shaft and capable of being locked thereto by clutches OO. The sprocket N communicates motion by means of a chain to a sprocketK on the shaft of the drum K. Gear-wheels 70 It communicate motion fromsaid drum to a brake-wheel P, over which passes a friction-band 9,attached to a lever P, by which the speed of the brakewheel and drum canbe governed. Anotched plate p holds the lever in any desired position.The sprocket N communicates motion by means of a chain to asprocket-Wheel Q on the shaft of a drum Q, suitably journaled onstandards a. On this drum is wound the rope E, which runs over a pulleyat the top of the shears, and is attached to the slushbucket, by meansof which the well is cleaned of the drill-cuttings.

Hinged at the end of the frame opposite to the shears B is awalking-beam R, which is capable of vertical oscillation. It is composedof a frame of timber, shaped like an A, laid on one side, as shown, andis strengthened by a tie-rod r. The lower leg of the A is shorter thanthe upper leg, and its end is preferably bound with iron 1'. The upperleg plays between guides S, which are provided with a buffer s such as ablock of rubber-to receive and break the force of the upward strokes ofthe beam R. The walking-beam is connected with the lever G by a link g,so that the movements of the beam are imparted to the lever.

The weight of the drill is sufficient to keep the lever Gand the beam Relevated as high as the buffer 3 will allow. In order to draw down thebeam and the lever, and thereby lift the drill by taking up a fold inthe rope D, the main shaft L is provided with a crank or trip T, looselymounted on the shaft and composed of a hub having two parallel arms t,in each of which are two or more holes to receive the adjustablewrist-pin t. On one end of the hub are formed lugs 25 to engage with aclutch U 011 the shaft L. Vhen the clutch is thrown into engagement withthe crank, the latter will be coupled to the shaft and will revolve inthe direction of the arrow in Fig. 4. At every revolution the wrist-pin25 will strike upon the iron-bound end of the beam R and carry it down,together with the lever G, thereby producing a downward pull on the ropeD and lifting the drill. WVhen the wrist-pin t passes off the end ofthelower leg of the beam R, the drill will be free to fall, and the beamR will rise until it strikes the bufier s. In this way the drill will bealternately lifted and dropped.

The main advantage of my construction is that the drill can be instantlystopped by throwing off the clutch II. This is a feature not possessedby any other similar machine with which I am familiar. Furthermore, theadjustable wrist-pin t enables the length of stroke of the drill to bevaried.

By releasing the lever P and letting the rope D unwind the drill can belowered, or by throwing the clutch 0 into operation the drill can beraised. In the same way the clutch 0' enables the slush-bucket to beraised or lowered by means of the rope E. The levers that operate theclutches O, O, and U and control the friction-brake 1) all terminate atthe front of the machine close to where the drill is at work, and wherethey are readily accessible to the operator in charge of the machine.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, 1s-

1. A well-drilling machine having a walking-beam, a main shaft, a crankloosely mounted on the shaft and provided with an adjustable wrist-pin,and a clutch sliding on the shaft and adapted to rigidly couple thecrank to the shaft, substantially as described.

2. The combination, with the crank-shaft of a well-drilling machine, ofa walking-beam composed of an A-shaped frame R, having the lower legarranged to be acted upon by the crank and the upper leg adapted toimpart movement to the drill, the beam being strengthened by a tie-rod 4between the two legs and hinged to the frame of the machine near themeeting-point of the two legs, sub-' stantially as described.

The combination, with the crank-shaft of a well-drilling machine, of anA-shaped walking-beam R, hinged to the frame at its apex and adapted tobe actuated by the crankshaft, guides S between which the beam plays,and a bulfer s to check the upward movement of the beam, substantiallyas described.

4:. The combination, with the shears 13, pro vided with a.pulley at thetop and with the shaft H near their base, of the horizontal lever G,hinged on the shaft H and carrying the pulley F, the pulley I on theshaft H, the rope D, passing around the pulleys I and F and over thepulley at the top of the shears, the walking-beam R, connected with thelever G, and means for actuating the walking-beam, substantially asdescribed.

5. A well-drilling machine provided with a main power-shaft, awalking-beam, and a Windingdrum for the drill-rope, the main shafthaving loosely mounted thereon a crank for actuating the walking-beam, awheel for communicating power to the Winding-drum, a clutch sliding onthe shaft and adapted to lock the crank rigidly to the shaft, and asecond independently-operated clutch sliding on the shaft and adapted tolock the wheel rigidly to the shaft, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.
